我使用安装了redis
sudo apt-get -y install redis-server
默认数据目录是/var/lib/redis/，但是当我在文件：sudo gedit /etc/redis/redis.conf中切换到另一个目录/some path/redisDB时，我无法再次启动redis服务器。我收到一个错误
Job for redis-server.service failed because the control process exited with error code. See "systemctl status redis-server.service" and "journalctl -xe" for details.
systemctl status redis-server.service
